Unfortunately, it's not that simple. Under Xen, a network device must be explicitly configured to be either PV or HVM. There is no mapping between PV and HVM devices. A single domain could have both an xnf0 and an rtls0 simultaneously. In such a domain, the two devices could connect to different physical NICs on the back end, and they could be on different subnets. Within the domU, we don't have enough information to draw any inferences about network topology. Any guesses we made about a sensible renaming scheme would likely go wrong under all but the simplest scenarios. Nils
